I guess he wants to play us then.
I can see where he's coming from. Crawford is revealing weaknesses within the team by saying they had air which required cleaning. It shows that their mindsets are in the wrong place, and they're not just going out and playing. They should have faith in their system, and anything they have to work on should be taken care of in practice.
I think if the captain wants to take the team out to dinner for bonding like Rondo did, that's cool. But it shouldn't be a "meeting" to hide from their coach and talk shop in private because everybody needs to get on the page. That's just a sign of bad chemistry, and according to Doc, puts a target on your back.
